We are planning to switch our environment from workgroup to domain (active Directory services).
We are planning to register our top domain at some public register.
That domain is going to be used just for ActiveDirectory and internals.
We are planing to use simple domain name as possibile
My DNS is going to be at private subnets and private IP addresses. When I do register my domain, registrar is going to ask me for DNS servers. Shodu I give them my local DNS servers for public registers ? Or is better to by some www reachibile DNS like AWS route 66 and point my domain to that DNS after that on that DNS server do redirect to local DNS servers. Or it is OK to do public register domain whit private DNS servers.
